Sulfuric Acid into Water and IceWhen sulfuric acid is mixed with water the temperature rises. When sulfuric acid is added to ice, the temperature rises at first, but as the ice melts, the temperature falls.

Calorimetry / Thermochemistry

Endothermic ReactionSolid barium hydroxide octahydrate (Ba(OH)2*8H2O) and ammonium thiocyanate (NH4SCN) are mixed in a beaker, which is then placed on a few drops of water on a small board. The reaction that occurs is highly endothermic.

Thermochemistry : SystemSurrExoEndo (4 Variations)
Sulfuric acid is added to water in a beaker and the resulting solution is much warmer than either the water or acid was initially.
Identify the following items as being part of the system or the surroundings, and indicate whether the process is exothermic or endothermic.

An Inexpensive Solution CalorimeterEmma Kavanagh, Sam Mindel, Giles Robertson, and D. E. Peter HughesDescribes the construction of a simple solution calorimeter, using a miniature bead thermistor as a temperature-sensing element, that has a response time of a few seconds and made it possible to carry out a thermometric reaction in under a minute.Kavanagh, Emma; Mindel, Sam; Robertson, Giles; Hughes, D. E. Peter. J. Chem. Educ.2008, 85, 1129.

ACS Scholars ProgramACS awards renewable scholarships to underrepresented minority students who want to enter the fields of chemistry or chemistry-related fields. Awards of up to $5,000 are given to qualified applicants based on academic standing, financial need, career objective, leadership skills, and involvement in school activities and community service
